Hydromyles species are pelagic, carnivorous and viviparous.
Description
The small pelagic snails lack shells (except in their early embryonic stage). They are carnivores, equipped with swimming parapoda (fleshy, wing-like outgrowths), strong jaws and grasping tentacles, often with suckers resembling those of cephalopods.
Genera and species
Genera and species within the family Hydromylidae include: Genus Hydromyles Gistl, 1848
- Hydromyles globulosus (Rang, 1825)
- Distribution: East Pacific, North America, western Atlantic.
- Description: This pteropod seizes its prey with its radula. Contrary to most gymnosomatiids, this pteropod has no proboscis and no hooks. It is also unique by having, close to the anal aperture, a sac for hatching its eggs. The larvae develop in this sac and are born as fully developed snails. In other words, this species is viviparous.

gollark: If the software updates are made on a different continent and you can apply them in less than about 50ms, you don't even need the time travel - just transmit them directly to your computer via a trans-crustal neutrino beam. Neutrinos travel only very slightly slower than light, and can take a more direct path because they don't interact much with matter, while the fibre-optic lines for internet traffic only let light go at 0.6c or something, and use less direct paths, and have routing overhead.
gollark: You did not specify that they were stolen from evil people, and possibly yes.
gollark: I'm not an EVILDOER!!!!!
